What is the mixture of iodine and sand?
The correct option is B that is SUBLIMATION. It is because iodine is a sublime substance that is, it is converted directly into vapours when it is heated without going into the liquid state. Whereas sand in non sublime.
Which method is used to separate iodine and sand?
Answer: Deepu use sublimation to separate the iodine and sand because iodine is a sublime substance that is, it is converted directly into vapour when it is heating without going into the liquid state.
What happens when he adds liquid iodine to hot sand?
Answer: When solid iodine crystals are heated (in a beaker with hot sand) the iodine will change from a solid directly to a gas without passing through a liquid phase. This is called sublimation. You can see in the video that a purple gas is formed when the iodine hits the hot sand.
How would you separate a mixture of sand and iodine crystals into its components?
Distillation refers to the process of using heating and cooling to separate and purify the components of a liquid mixture.
How would you separate a mixture of iodine sodium chloride and sand?
Explanation: ans15:PROCESS INVOLVE – Sublimation. Due to Sublimation, iodine and sodium chloride will change into gas and sand will be separated out.
Is iodine is a sublime substance?
Iodine provides an excellent example of sublimation. Visible purple gas is formed when iodine sublimation. When solid iodine crystals are heated the iodine changes from a solid directly to a gas without passing through a liquid phase. Hence iodine undergoes sublimation.
How can we separate a mixture of sand and Sulphur?
Mixture of sand and sulphur may best be separated by Dissolving in CS2 and filtering. Sand and Sulphur powder is collected and dissolve it in Carbon disulphide (CS2). Sand is insoluble in carbon disulphide whereas sulphur is soluble in carbon disulphide.
How would you separate sand sodium chloride and iodine crystals?
Sublimation is the best method for separating iodine from common salt (NaCl). Since iodine is sublimable, it will change to vapour state directly from solid when heated slightly and the iodine vapours can be collected while common salt remains as such. Answer: Best way is sublimation.
How can we separate sand and water?
It is easy to separate sand and water by filtering the mixture. Salt can be separated from a solution through evaporation. The water can also be recovered as well as the salt if the water vapour is trapped and cooled to condense the water vapour back into a liquid. This process is called distillation.
